chinese firedrill is when a car comes to a red light, someone yells "chinese firedrill!!", somebody has to get out and run around the car (doesn't matter who, "not it" works) and get back in before the light turns green.
If the light turns green before the person is back in the car, the driver drives off. this gets especially amusing when someone locks the doors.
Nate was stranded when he didn't make it back in the car during the chinese firedrill.
